After covering Plato and Aristotle in my political philosophy seminar here, I assigned my students their first paper. I wrote the assignment in English. My (human) translator Amer translated it into Arabic and posted it on the class’s website–a closed group site on Facebook. Facebook then automatically had the assignment re-translated back into English via Google Translate. And that’s when all hell broke loose.
Aeon has an interesting piece by psychologist Robert Epstein on why the brain is not a computer. In one sense, this is just a truism. Computers are machines made by human beings, whereas brains are animal organs that have evolved over a very long period of time; computers are made of metal chips, brains aren’t; computers aren’t neurochemical, brains are; brains can do lots of things that computers can’t (yet, anyway); and so on. This truism, though, depends on a rather imprecise, colloquial sense of the word ‘computer.’ More strictly speaking, a computer is just any device that computes, that is, “performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.”1 In this sense, many cognitive scientists believe that the brain is literally a computer. While it is of course not a ‘device’ designed by human beings, it nonetheless performs mathematical and logical operations and assembles, stores, correlates, and more generally processes information. Indeed, to many people, and not just cognitive scientists, it might seem that the truism is that the brain is a computer in this sense.
